Nyayadarshan (1, 2, 3) refers to the principles of the fourfold proof as mentioned in Tattvartha, verse 1, sutra 6 and 35 in its commentary. The distinction of the proofs such as Arthapatti, Sambhava, and Abhava in Tattvartha commentary 1, 12 is similar to Nyayadarshan (1, 2, 1). In Nyayadarshan, the term “indriyasannim” (1, 1, 4) is present in the definition of the direct. In Tattvartha commentary 1, sutra 12, the same term is used while including concepts like Apatti, which are considered distinct in Mati and Shruta knowledge. For instance, "सर्वाण्येतानि मतिश्रुतयोरन्तभूतानि इन्द्रियार्थसन्निकर्षनिमित्तत्वात्।।" In the same way, the practice of using the term Anarthantra in place of Paryay in Patanjali's Mahabhashya and Nyayadarshan (1, 1, 15) is also present in Tattvartha Sutra (1, 13).
The specific views or unique terms of the branches such as the Buddhist doctrine of Shunyavada and Vijñanavada do not have references in the Tattvartha commentary as they are in Sarvarthasiddhi; however, the general views of Buddhist philosophy appear in contexts like Sankantran. These views are derived from either the Pali Pitaka or from Mahayana-created Sanskrit Pitaka or from other textual sources.
